Discontinuous Reception Command Over Sidelink

2. The method of claim 1, wherein stopping monitoring of the PSCCH comprises entering a sleep mode in response to not being in a DRX active state for a link with the base station.

3. The method of claim 1, wherein the sidelink DRX command is a sidelink control information (SCI).

4. The method of claim 1, wherein the sidelink DRX command is a sidelink media access control (MAC) control element (CE).

6. The method of claim 5, wherein informing the base station that the portion of the PSCCH/PSSCH occasion is unused comprises transmitting a scheduling request informing the base station that the portion of the PSCCH/PSSCH occasion is unused when the first UE has uplink data to transmit to the base station, the method further comprising transmitting an uplink transmission on unused resources of the PSCCH/PSSCH occasion.

9. The method of claim 8, wherein informing the second UE of the duration of the DRX active state comprises informing the second UE of a remaining duration of the DRX active state after a prohibition time measured from the sidelink DRX command.

10. The method of claim 8, further comprising receiving PSCCH and PSSCH from the second UE during the duration of the DRX active state.

12. The apparatus of claim 11, wherein the at least one processor is configured to enter a sleep mode in response to not being in a DRX active state for a link with the base station.

13. The apparatus of claim 11, wherein the at least one processor is configured to inform the base station that a portion of the PSCCH/PSSCH occasion is unused in response to not being in a DRX active state for a link with the base station.

15. The apparatus of claim 14, wherein the at least one processor is configured to inform the second UE of a remaining duration of the DRX active state after a prohibition time measured from the sidelink DRX command.

16. The apparatus of claim 14, wherein the at least one processor is configured to receive PSCCH and PSSCH from the second UE during the duration of the DRX active state.

17. The apparatus of claim 11, wherein the sidelink DRX command is a sidelink control information (SCI).

18. The apparatus of claim 11, wherein the sidelink DRX command is a sidelink media access control (MAC) control element (CE).

20. The apparatus of claim 19, wherein the means for stopping monitoring of the PSCCH is configured to determine to enter a sleep mode in response to not being in a DRX active state for a link with the base station.

21. The apparatus of claim 19, further comprising means for informing the base station that a portion of the PSCCH/PSSCH occasion is unused in response to not being in a DRX active state for a link with the base station.

22. The apparatus of claim 21, wherein the means for informing the base station that the portion of the PSCCH/PSSCH occasion is unused is configured to transmit a scheduling request informing the base station that the portion of the PSCCH/PSSCH occasion is unused when the first UE has uplink data to transmit to the base station, the apparatus further comprising means for transmitting an uplink transmission on unused resources of the PSCCH/PSSCH occasion.

25. The apparatus of claim 24, wherein the means for informing the second UE of the duration of the DRX active state is configured to inform the second UE of a remaining duration of the DRX active state after a prohibition time measured from the sidelink DRX command.

26. The apparatus of claim 24, further comprising means for receiving PSCCH and PSSCH from the second UE during the duration of the DRX active state.

28. The non-transitory computer-readable medium of claim 27, further comprising code to inform the base station that a portion of the PSCCH/PSSCH occasion is unused in response to not being in a DRX active state for a link with the base station.
